1B) (Matson 1986). Polarity is ascertained by identifying the duplex region that is denatured by the helicase. For helicases involved in DNA replication, the polarity of the reaction is strongly indicative of helicase placement on the leading (a 3 ' -5 'polarity) or lagging (a 5 +3 'polarity) strand.NA HELICASE ASSAYS DNA helicases are often first detected by a DNA-dependent or DNA-stimulated NTPase activity. Verification of DNA helicase activity is then accomplished using an assay that reveals the conversion of double-stranded DNA (dsDNA) into two single strands.
1. typical enlistment is 4 years, however during Vietnam 3 year enlistments were allowed. 2. The 3rd Marine Division was reactivated for Korea, and in 1956 moved to Okinawa as the cease fire there looked like it would hold. Air Bases remained active in Okinawa during the entire postwar and Cold War era to date.
Here are statistics from the Combat Area Casualty File (CACF) as of November 1993. The CACF is the basis for the Vietnam Veterans Memorial (The Wall): Average age of 58,148 killed in Vietnam was 23.11 years. (Although 58,169 names are in the Nov. 93 database, only 58,148 have both event date and birth date.
